反刍动物甲烷排放测定和营养调控减排方法

Research status about methane emission determination from ruminant and techniques of nutritional control and emission reduction

反刍动物瘤胃内甲烷的产生是饲料能量的浪费,同时还增强了温室效应。因此减少反刍动物甲烷排放对保护环境和提高能量利用率均有重要意义。文章对瘤胃甲烷生成机制、排放量测定方法和营养调控进行概述,就如何减少甲烷排放进行了讨论,旨在为通过日粮营养调控措施来降低甲烷排放提供参考。

Methane produced by ruminants contributes to global greenhouse effect and causes loss of feed energy. Therefore, it has a great significance for improving energy utilization of ruminants and environmental protection to take effective measures to alleviate methane emissions from ruminants. This paper reviews the mechanism of methane production, the determination method of methane emission from ruminants and nutritional control techniques, discusses how to reduce methane emissions, and aims to provide references for reducing methane emissions through dietary nutrition regulation measures.
